teepee 
Wrap your command in a teepee and capture its output while also piping it to the parent process
stdout and stderr.
use std::process::Command;
use teepee::Teepee;
fn main() {
let mut command = Command::new("ls");
command.arg("-l").arg("-a");
let mut teepee_cmd = Teepee::new(command);
eprintln!("\nCommand running ...\n");
match teepee_cmd.output() {
Ok(output) => {
eprintln!("\nCommand executed successfully.\n");
let stdout = String::from_utf8_lossy(&output.stdout);
let stderr = String::from_utf8_lossy(&output.stderr);
eprintln!(
"Captured stdout (lines: {}):\n> {}",
stdout.lines().count(),
stdout.lines().collect::<Vec<&str>>().join("\n> ")
);
eprintln!(
"Captured stderr (lines: {}):\n{}",
stderr.lines().count(),
stderr
);
}
Err(e) => {
eprintln!("Error executing command: {}", e);
}
}
}
This example prints the output of the ls -l -a command while it is running and then again the
captured output prefixed by > .
